Co-dynamics of hepatitis B and C viruses under the influence of CTL immunity

Alexandria Engineering Journal
Understanding the cytotoxic T lymphocyte (CTL) immune response against hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is crucial, as these infections can lead to liver cirrhosis and cancer. Mathematical models provide valuable support for

A memory-driven pneumonia dynamics model validated against Ethiopian mortality data: a fractional-order differential equation framework

Scientific Reports
Every year, pneumonia kills millions across the globe, disproportionately claiming the lives of children under five and immunocompromised adults in low-resource settings, yet the mathematical tools deployed to understand and contain it remain ...

Stability of generalized models for HIV-1 dynamics with impaired CTL immunity and three pathways of infection

Frontiers in Applied Mathematics and Statistics
Highly active antiretroviral therapy (HAART) stands out as the most effective treatment for human immunodeficiency virus type-1 (HIV-1). While total eradication is still difficult, HAART can dramatically lower the virus's plasma viral level below the ...

Optimal control efforts to reduce the transmission of HPV in a fractional-order mathematical model

Boundary Value Problems
Human papillomavirus (HPV) is a sexually transmitted virus that causes cervical cancer in women and leads to death. In this research paper, we prepare a fractional mathematical model that contains a system of four fractional differential equations (FDEs)

Stability analysis of a diffusive HTLV-2 and HIV-1 co-infection model

Alexandria Engineering Journal
Co-infections between human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic virus type 2 (HTLV-2) are more common, particularly among injection drug users and individuals engaging in sexual activity.

Qualitative analysis and optimal control of a dengue model with asymptomatic transmission

Discover Public Health
Dengue fever remains one of the most rapidly expanding vector-borne diseases worldwide, driven by complex interactions between host, vector, environment, and increasingly, human mobility.

Global Dynamics of a Dual-Target HIV Model with Time Delays and Treatment Implications

Mathematics
We present a comprehensive mathematical analysis of a within-host dual-target HIV dynamics model, which explicitly incorporates the virus’s interactions with its two primary cellular targets: CD4+ T cells and macrophages.
